ExpatError：文檔元素後的垃圾

Question

我真的不知道，問題是什麼？我收到以下錯誤：

File "C:\Python27\lib\xml\dom\expatbuilder.py", line 223, in parseString 
parser.Parse(string, True) 
ExpatError: junk after document element: line 5, column 0 

我看不到垃圾！任何幫助？我越來越瘋狂......

text = """<questionaire> 
<question> 
    <questiontext>Question1</questiontext> 
    <answer>Your Answer: 99</answer> 
</question> 
<question> 
    <questiontext>Question2</questiontext> 
    <answer>Your Answer: 64</answer> 
</question> 
<question> 
    <questiontext>Question3</questiontext> 
    <answer>Your Answer: 46</answer> 
</question> 
<question> 
    <questiontext>Bitte geben</questiontext> 
    <answer>Your Answer: 544</answer> 
    <answer>Your Answer: 943</answer> 
</question> 
</questionaire>""" 

cleandata = text.split('<questionaire>') 
cleandatastring= "".join(cleandata) 
stripped = cleandatastring.strip() 
planhtml = stripped.split('</questionaire>')[0] 
clean= planhtml.strip() 


from xml.dom import minidom 

doc = minidom.parseString(clean) 
for question in doc.getElementsByTagName('question'): 
    for answer in question.getElementsByTagName('answer'): 
     if answer.childNodes[0].nodeValue.strip() == 'Your Answer: 99': 
      question.parentNode.removeChild(question) 

print doc.toxml() 

Thanx！

您的原始text字符串是格式良好的XML。然後你做了一堆東西來打破它。解析你的原始text，你會沒事的。

XML必須只有一個頂層元素。當你解析它時，它有一些頂級的<question>標籤。 XML解析器將第一個解析爲根元素，然後驚奇地發現另一個頂級元素。
